TRAFFIC INDICATOR.

Application led December 30, 1921. Serial No. 525,842.'

To aZZw/wm z't may concern:

Be it known that I, l/VILLIAM D. KYLE, a citizen of the United States,and resident ofl Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented new and useful Improvements in TrafficIndicators, `of which the following is a description, reference beinghad to the accompanying drawings, which are a part of thisspecification. The invention relates to traflic lights. A The object ofthe invention is to provide a traiiic light of simple and inexpensiveconstruction and adapted to be mounted within the pavement or road atstreet intersections of) other places where an indicator is desira. le.l

The invention further consists in the several features hereinafter setforth and more particularly defined by claims at the conclusion hereof.i

In the drawings: Fig. 1 is a vertical sectional view through a deviceembody-ing the invention;.Fig. 2 is a plan view thereof; Fig. 3 is adetail sectional view showing a modified form of cap connection; Fig.` 4is a plan view of the structure shown in Fig. A3. In the drawings thenumeral 5 desi ates a member forming the base and guar portion of thedevice.

The base portion of this member is preferably circular and provided witha .centrally disposed cup-shaped portion 6 forming a lamp casing inwhich the lamp recepvided with a screw thread to engage the threadedportion 21 of the cap to form a detachable connection, spaced Spannerwrench openings 22 being provided in the top of the cap for turning it.In Figs. 3 and 4 I show apertured ears 23 on the cap through whichscrews 24 pass to detachably secure the cap in position.

An electric lamp 25 is mounted inthe receptacle 7 with its bulbprojected above the base of the device so that its light rays will passthrough the openings 17 of the guard.

In order to protect the lamp from the elements and from foreign matter alantern globe 26, surrounding the bulb, is provided. This globe ispreferably a cylindrical member, preferably of thick glass, having i'tslower edge seated in an annular recess 27 in the base and its upper edgeseated in ,an annular recess 28 in the cap, compressible packing rings29 being seated in these recesses to'prevent injury to the globe when itis clamped in positionby the attachment of the 'cap 20.

The cap 20 is provided with a conical reector portion 30 adjacent thetop of the globe so as to assist in directing the light rays outwardlyin radial directions along the surface of the roadway in which thedevice is installed.. The removal of the cap 85 permits ready removal ofthe lamp or globe in case replacements or cleaning is necessary.' Theglobes 25 may be replaced at small ex- 1o ed tacle 7 is mounted upon apipe nipple 8 which connects with .a conduit 9 through which theconductor 10 carrying the current wires 11 and 12 passes. y.The lowerend of pense. D n

I desire it 'to be understood that th1s .1nvention is not to be limitedto any speclfic form or arrangement'of parts except in so the portion 6is provided with a laterally extending anchoring flange 13 and the outerportion of the base is provided withy a depending annular Hange 14. Theflange 13y serves to anchor the device in the `concrete foundation ofthe roadway and the flange 14 also serves as an anchor to preventlateral displacement of the device. The guard portion`of the member 5in` cludes a conical outer wall 15 extending fromI the outer edge of thebase to a circular top 1G, said wal-l having radially extending,openings 17 therein and being reinforced by vertically disposed spacedribs 18 extending from the base to a position adjacent the top 16. Thetop has a centrally disposed opening 19 covered by a removable cap 20.In F igs. 1 and 2 I .show the opening 19 profar as such limitations arespecified in the` claims.

What I claim asmy invention is:

1. In a traiicv indicator, the combination of a base, a guard `havingaperture'd inclined walls and an opening in its top, a removable cap forsaid opening, a lamp receptacle mounted in the base, an electric lamp insaid receptacle, and a globe surrounding the bulbof said lamp andclamped between said cap and base.

2. In a traffic indicator, the combination of a circular base, a conicalard having an -apertured wall and an openingl in its top, a removablecap for said opening, a lamp receptacle mounted in the base, an electriclamp in said receptacle, and a globe sur- -rounding the bulb of saidlamp and clamped 11o between said cap and base, said cap having aconical reflector portion adjacent said lamp. y

3. In a tra'ic indicator, the combination of a member having a circularbase portion provided with a depending centrally disposed cup portionand a conical guard portion provided with side openings and a centraltop opening, a removable cover cap for said central opening, said caphaving an annular recess therein and said base portion having an annularrecess therein adjacent said cup portion, a cylindrical glass globehaving its upper and lower edges seated in Leraars said recesses, alamp' receptacle in said cup 15 and an electric lamp mounted 1n lportion, said receptacle and having its bulb surrounded by said globe.

4. In a trailic indicator, the combination of a base, a lamp receptaclemounted in the base, an electric lamp in said receptacle, a cylindricalglobe surrounding the bulb of said lamp, `an apertured guard for saidglobe, and means for clamping the globe against the base.

In testimony whereof, I aix my signature.

WILLIAM D. KYLE.
